Active Learning vs Passive Learning: Feelings of Learning? After the active learning or passive learning class, students rated the extent to which they agreed with the statement “I feel like I learned a great deal from this class.” Ratings were on a 5-point scale with greater numbers indicating greater agreement. For the 142 students in the active learning environment, the mean rating was 3.338 with a standard deviation of 0.922. For the 154 students in the passive learning lecture, the mean rating was 3.753 with a standard deviation of 0.873. Test whether ratings on feelings of learning are significantly lower, on average, with active learning. (Let Group 1 represent active learning and Group 2 represent passive learning.)

Question Help ▼ A study on the personality characteristics of drug dealers sampled 100 convicted drug dealers and scored them each on the Wanting Recognition (WR) Scale, which provides a quantitative measure of a person's need for approval and sensitivity to social situations. (Higher scores indicate a greater need for approval.) The sample of drug dealers had a mean WR score of 56, with a standard deviation of 5. Use this information to find an interval estimate of the mean WR score for all convicted drug dealers. Use a confidence level of 99%. Interpret the result. Construct a 99% confidence interval and interpret the result. (Round to two decimal places as needed.) O A. The 99% confidence interval for mean WR score indicates that the true mean WR score for convicted drug dealers is between and with 99% confidence. O B. The 9g9% confidence interval for mean WR score indicates that 99% of all drug dealers have a WR score between and and. O C. The 99% confidence interval for mean WR…
